ToaZZ whom tmay cenicero-i.:

Be it known that we, WL'rnR and JOHNA L.` FrrzrarRIoK, Icitizens ofjthe United States, residing at Parkerton, inthe.

It is oftenL found necessary ;toj remove from an oil well theWQvllin'g barrel and in doing so under the present practice considerable oil is wasted and spilled from the barrel when it is raised to the top of the well thereby greatly increasing the fire danger and also messing up the platform as well as tools and other articles thereon to the great inconvenience of the workmen.' The purpose of the present invention, therefore, is to eliminate this wastage of oil and also the inconveniences incident thereto. We realize that some other devices have been invented and patented with the same end in view but to our knowledge none of these devices have ever reached the market or proved practical in operation.

Another important object of the invention is to provide a device of this nature which will be simple and eicient in construction, reliable in operation, durable, and Well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description progresses, the invention resides in certain novel features of construction, and the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing- Figure 1 is a section through an assemblage embodying our invention,

Figure 2 is adetail section through the lower end thereof,

Figure 3 is a transverse section taken substantially on the lineB-S of Figure 1 looking in the direction of the arrow,

Figure 4 is a detail transverse section y Referring t0, ,thadawieg taken substantially ..011. thefln ffae0i taken .Substantially 9.1.1 .they-lin@- 5 urepwl .lookingLinthadirection u the arrow l data' beseen'that the lower portionvlofgthe ,w rk inet-barret 1.11asfbeeai1lustaatd @shrouded Casina ,havinga Cas@ 4.

A swed'ge nipplewty is provided Vat its larger end with threads engageable with the lower end of the coupling 2. A coupling 7 is threaded to the' smaller end of the nipple 6 for connecting it to a shell 8 whichv is partially closed at its lower end as at 9 while the upper end thereof is partially closed by a bushing 10 threaded therein. An anchor connection or inside pipe v11 is movable through the shell 8 and is provided with an extension 12 which extends into the nipple 6 and has fixed thereto a rod'lll ex- Y Vtending through the standing valve casing 3.

vided with the longitudinally extending,

slots 16 having the angular extensions 17 at their upper ends. These slots 16 are diametrically opposed to each other and receive the pins 18 which are threadedly engaged with the anchor connection or inside pipe and preferably with the extension 12 thereof as is indicated to advantage in Figure 2. The extensions 12 is threadedly engaged with the anchor connection 11 and atY its bottom end is provided with a collar 20 spaced from which is also provided a collar 21 and it is to be noted that the pins 18'are disposed between these collars. The collar 20 is adapted to engage theV closure member 9 of the shell 8 so that the weight ofthe working barrel and other parts will be on this collar 2O and the closure 9 rather than on the pins 18 when the working barrel is being lowered into the well and the anchor engages the j y u 55 i urgl lookingl inthe direction ofthefarroW, an

v10o Y i cclnliection to telescope in regard to the outer s e In assembling the device the bushing 10 is removed from the shell 8 and the anchor connection may be'inserted from the top of the shell and the bushing replaced after which the coupling collar 7 may be screwed in position for receiving the swedge nipple. The assembling of the other parts is quite self-evident from an` inspection o1' the drawmg.

In using our device when itis desired to remove the working barrel for any reason it is first lowered so as to telescope the anchor connection in relationv to the shell 8 and when the pinsarrive at the top of the slots 16 the barrel is slightly rotated to the right causing thepins to be lowered in the angular extensions 17.' Y Y Although we have described our invention with some degree of particularity it is to be understood that the preciseV embodiment here shown has'merely been given by way of example and that numerous changes in the details of construction and in the combination and arrangement of parts may be resorted towithout departing from the spirit of the invention as hereinafter claimed.

Having thus described our invention what we claim as new is In combination, a working barrel, a standing valve in the working barrel, a shell attached to the working barre] at its bottom end and provided with longitudinally eX- tending slots having angular extensions at their upper ends, an anchor connectionV movable in the shell and including a member engageable with the` standing valve for unseating the same when the working barrel is lowered, pins projecting from the anchor connection and movable in the slots of theY shell, the bottom end of said` shell being partially closed, a. removable bushing in the upper end o said shell, a shoulder on said anchor connection .adapted to abut the partial closure at the lower end so that the weight of the barrel and other parts will be on said partial closure and shoulder rather than on said pins.

In testimony whereof we aix our signatures in presence of two witnesses.
